What is the Slope of these two points (6,2) and (9,5)
Daniel [21]

Answer: 1

Step-by-step explanation:

You would use the slope formula which is (y2-y1)/(x2-x1) where x1 and y1 correspond to the first point and x2 and y2 correspond to the second point. This would be (5-2)/(9-6) which equals 1. Hope this helps!

Which of the following is equivalent to (2x + 3)(2x + 3)?
Kryger [21]

Answer:

(2x+3)(2x+3)=4x^2+12x+9

Step-by-step explanation:

we are given

(2x+3)(2x+3)

Firstly, we will distribute it

=2x\times 2x+2x\times 3+3\times 2x+3\times 3

now, we can simplify it

=2\times 2\times x\times x+2\times 3x+3\times 2x+9

=4x^2+6x+6x+9

=4x^2+12x+9

so, we get simplified term as

(2x+3)(2x+3)=4x^2+12x+9

Find f(0) and f(2) for the given exponential function. f(x) = (1/2)^-x
Aliun [14]
For 0 it will equal 1 because anything to the 0th power is 1 except 0 to the 0.

For 2, It will equal for because when you raise a fraction to the negative power you flip it and that gets rid of the negative number so then you will have 2 to the second and you will get 4.

f (0) = 1, f (2) = 4

Find the exact value of sine [2 cosine Superscript negative 1 Baseline (- StartFraction StartRoot 2 EndRoot/2 EndFraction )] = n
Nady [450]

Answer:

\frac{3\pi}{2}.

Step-by-step explanation:

The given expression is

2\cos^{-1}\left(-\frac{\sqrt{2}}{2}\right)

It can be rewritten as

2\cos^{-1}\left(-\frac{1}{\sqrt{2}}\right)

2\left [\pi-\cos^{-1}\left(\frac{1}{\sqrt{2}}\right)\right]            [\because \cos^{-1}(-x)=\pi-\cos^{-1}(x), x\in [-1,1]]

2\left [\pi-\cos^{-1}\left(\cos \frac{\pi}{4}\right)\right]

2\left [\pi-\frac{\pi}{4}\right]

2\left [\frac{4\pi-\pi}{4}\right]

\frac{3\pi}{2}

Hence, the exact value of given expression is \frac{3\pi}{2}.
